CLEANER FOR COTTON-GIN SAWS.

SPECIFICATION forming part of Letters Patent No. 404,616, dated June 4, 1889.

Application filed September 27, 1888. Serial No. 286,578. (No model.)

To all whom, it may concern:

Be it known that 1, JOHN CALHOUN GOD- WIN, of Lloyd, in the county of Denton and State of Texas, have in vented a new and 1111- proved Cleaner for Cotton-Gin Saws, of which the following is a full,- clear, and exact de-- scription.

The object of the invention is to provide a new and improved cleaner for removing gummy and other matter from the saws of cotton-gins while the latter are running, thus permitting the saws to work very effectively in removing the lint from the seed.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed outin the claims.

Reference is to behad to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectionalside elevation of part of a cotton-gin provided with my improvement on the line new of Fig. 2. Fig. 2isatransverse section of the same on the line y y of Fig. 1. Fig. 3 is a plan view of the improvement. Fig. Al is a sectional side elevation of the same on the line ,2 z of Fig. 3', and Fig. 5 is a like view of the same on the line 10 w of Fig. 3.

The cotton-gin A, of any approved construction, is provided with the usual number of saws B, secured on a shaft 0, mounted to rofate in the usual frame D of the cotton-gin. Directly below the saws B is placed the cleaner E, consisting, principally, of a drum F, provided with radially-arranged pairs of arms G, forming forks and adapted to press against the faces of the saws B, as is plainly shown in Fig. 2. The pairs of arms G usually employed for one saw number about four, and are made of a spring material, such as horn, whalebone, &c. The material employed for the pairs of arms G must be such as not to cause lire when coming contact with the rotating saws B, and hence the above-mentioned material best answers the purpose.

The drum F is fastened on a shaft H, mounted to rotate in suitable bearings formed in the plates l l at each end of the drum, and mounted to slide vertically in suitable guideways formed in the standards J J, secured on the frame K, fastened to the frame D of the cotton-gin, as is plainly shown in Figs. 1 and 2. Instead of making the frame K and its parts separate from the frame of the cottongin, they may form part of the latter.

On the inner side of each vertically-sliding plate 1 is formed a pin, L, held in cont-act with the face of a cam N, secured on a shaft 0, mounted to rotate in suitable bearings in the standards J and passing through the frameD of the cotton-gin A. The cams N arepreferably made by forming an eccentric groove in the outer side of each of two disks, and when the cams are turned to throw their points of greatest eccentricity upward the pins L, plates I, and drum F will be raised, as stated. On one outer end of the shaft 0 is secured ahand-' wheel P for turning the said shaft 0, so as to raise by means of the cams N and the pins L the plates l, and consequently the drum F and its arms G. On the periphery of one cam N is also formed a toothed segment N, engaged by a pawl Q, fulcrumed on the frame K and serving to hold the cam N in a locked position when raised.

On one outer end of the shaft H is held a friction-pulley R, adapted to engage a friction-wheel S, secured on the outer endof the shaft 0, carrying the cotton-gin saws B.

The operation is as follows: Vhen the cotton-gin A is running in the usual manner and gum or other matter has accumulated on the saws B, and the operator desires to clean the latter from said gummy matter, then he turns the hand-wheel P, so that the cams N, acting 011 the pins L, raise the plates I and move the drum F upward, so that the pairs of arms G press upon the faces of the saws B, as shown in Figs. 1 and 2. Then the drum F is moved 9c upward, the friction pulley R is moved in contact with the friction-wheel S, so that the rotation of the latter imparts a rotary motion to the pulley R and to the drum F, whereby the several pairs of arms G for one saw B come successively into contact with the faces of the said saw. The pulley R is considerably smaller in diameter than the friction-wheel S, so that the drum F is rotated at a higher speed than the saws B. As the pairs of arms G, on I00 account of their springy nature, are pressed firmly in contact with. the faces of the saws B,

the latter are thoroughly cleaned of all gummy matter. As soon as the saws are cleaned the operator turns the hand-wheel P in the opposite direction, having first released the pawl Q, so that the plates 1, supporting the drum F, are again moved downward into their former position and the pairs of arms G are moved out of contact with their respective saws B. The rotation of the drum F ceases the moment the latter moves downward, as the friction-pulley R is moved out of contact with the wheel S. Thus it will be seen that the saws B are cleaned while the cotton-gin is running without interfering with the working of the cotton-gin.

It will be seen that considerable time is saved with my improved cleaner, as the cotton-gin is not stopped while the saws are being cleaned. As the saws are kept clean, they very effectually remove the lint from the seed.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with the gin-saws, the saw-shaft, and a friction-pulley on said shaft, of a drum mounted to rot-ate and to slide vertically, arms held radially on the said drum and adapted to engage the faces of the saws, a pulley held on the said drum, and means, substantially as described, for moving the drum up and down so that the arms engage or are disengaged from the saws as the said pulley is moved into frictional contact with the saw-shaft pulley, so as to impart arotary motion to the drum, as set forth.

2. In a cleaner for cotton-gin saws, the combination, with a frame provided with standards, of plates held to slide in the said standards, a shaft journaled in the said plates, a drum on the said shaft, pairs of arms secured on the said drum, pins projecting from the said plates, cams operating on the said pins, and a shaft mounted to rotate in the said frame and carrying the said cams, substantially as shown and described.

3. In a cleaner for cotton-gin saws, the combination, with a frame provided with standards, of plates held to slide in the said standards, a shaft journaled in the said plates, a drum held on the said shaft, pairs of arms secured on the said drum, pins projecting from the said plates, cams operating on the said pins, a shaft mounted to rotate in the said frame and carrying-the said cams, and a handwheel for turning the said shaft, substantially as shown and described.
